(t^{2} + 3 t^{3} - 3) + (2 t^{2} + 7 t - 2 t^{3})

$(t^{2} + 3 t^{3} - 3) + (2 t^{2} + 7 t - 2 t^{3})$

Step 1

Remove parentheses.

t^{2} + 3 t^{3} - 3 + 2 t^{2} + 7 t - 2 t^{3}

$t^{2} + 3 t^{3} - 3 + 2 t^{2} + 7 t - 2 t^{3}$

Step 2

Add

t^{2}

$t^{2}$ and

2 t^{2}

$2 t^{2}$ .

3 t^{2} + 3 t^{3} - 3 + 7 t - 2 t^{3}

$3 t^{2} + 3 t^{3} - 3 + 7 t - 2 t^{3}$

Step 3

Subtract

2 t^{3}

$2 t^{3}$ from

3 t^{3}

$3 t^{3}$ .

3 t^{2} + t^{3} - 3 + 7 t

$3 t^{2} + t^{3} - 3 + 7 t$
